I agree, the best way to plot is to use a software with NetCDF support,
like Matlab or R.
But ARWpost is't a quick solution for GrADS users.
Cheers!

The ARWpost software also includes utilities (look in the util
subdirectory) that can make a .ctl file from your WRF history dump file so
you can view the raw output in Grads without first post-processing it.  It
would probably take you less time if you go this route, but you will have
to manually compute relative humidity in Grads then.  It isn't required of
you to compile or run ARWpost to use these utilities.

Dear All,

I am using 1.9b.
This software can produce polar map with stereographic projection
(nps/sps option).  I would like to produce it with orthographic
projection.

Is there any useful information/suggestion on this topic?

Thank you.

Using 'set mproj orthogr' command.

Dear Yaqiang,

Thank you for your suggestion.
Unfortunately, orthogr option does not support polar map projection, does 
it?

Did you mean the Orthographic projection with north pole as center?
Infact, this projection is controled by central meridian and reference
latitude, so you can set reference latitude as 90 to center the north
pole (a sample figure is attached). In GrADS, There is no options for
setting projection parameters. I guess it can be controled by using
'set lon' / 'set lat' commands, but I don't know how to deal with this
condition.
